With DisplayCal Profile loader already running in the background; i run an program that requires colors to be loaded or my calibrated profile from dispcalgui to be loaded, i get this error. Doesn’t happen in all programs naturally but it especially annoying with MPC-HC since it comes up every time i start a video.

  1. I have the same issue. Here is the full error message: C++ assertion “m_iconAdded” failed at ..\..\src\msw\taskbar.cpp(254) in wxTaskBarIcon::ShowBalloon(): can’t be used before the icon is created

    Log attached.

  2. Just now, I also encounterd this assert error. My repro was:

    1) windows 10 x64 laptop was sleeping
    2) I opened lid
    3) typed in password
    4) windows desktop appears and this same assert error

    Attached is my log file. It does show the assert in it.
